This is the 10th lesson in the Probability Unit. This lesson includes an introductory activity. The students will take samples of the same size and explore the sampling distribution. After the activity, students will determine if number is a parameter or a statistic, they will identify the difference between a population distribution, sampling distribution, and a distribution of sample data. Students will decide if a statistic is an unbiased estimator. Last they will make connections between the size of a sample and the variability of a statistic. These lessons are set up to have the teacher lead the students through the note-taking process while incorporating examples for the students to try. The answer keys are provided. Homework will be added shortly at not additional cost to those who purchase before. I will also be making videos that take the student through the lesson for those that flip their classroom or for absent students. SMART notebook files are included for the teacher to fill in with the class.
